Just stopped by my dealer to show that my fuel breather pipe is also showing some beginning of cracking at the top end (but not as bad yet as with Joao Pedro), and they confirmed to me that still last week they had a Defender in their shop with similar leakage as experienced by Joao Pedro, so had to replace this breather pipe.
Apparently it is not the end of the world of a job, they are able to slightly loosening the fuel tank just enough to be able to access the bottom end connection, so then it is an easy replacement. My truck has its scheduled maintenance there in a few weeks from now, and they will replace my cracking breather pipe then. Not under the extended warranty as nothing is leaking yet, but the breather pipe itself is cheap enough, and the labor will be less than an hour. My truck being almost 5 years old could be waiting to develop a similar leak, and I rather do some preventive maintenance here. Better safe than sorry  You never actually own a Defender. You merely look after it for the next generation.

Not sure if my big clumsy hands can do such precision work! But it a good tip!
Good to know! Just arranged with a mate to do this job at the end of next week! Four hands are better than two... I'll let you know how to goes!

Hmmm .. you only change the part of the pipe you can see and easily get at that way, donīt you? I have no real idea, but I would presume that the other - hard to get at - end of the pipe looks similar. Maybe there the cracks are less harmful, water wonīt get there too easily. But a leak could occur. OTOH a leak will be seen when itīs there. And then thereīs still time to change the lot. |

I think this is caused by the shape of the end of the pipe that the hose is fitted to. They hose clip tightens the hose as it should but the clip sits in a big depression causing strain on the hose end where it pulls over the wide part before the clip. I think that if the end or "lip" of the pipe was not as pronounced, this problem would not arise. 1982 88" 2.25 diesel

Landybehr, Slightly O/T, but could you post up the link to the thread where this originally appeared? I assume it's from a build thread on the blacklandy.eu German site? Reason I ask is I'm having 'issues' mounting a plastic TD5 tank in a metal-tank (TD-era) chassis, and it appears the photographer has a good shot of the exposed chassis with fuel system installed. Many thaks... Matt Real trucks don't have spark plugs |

Hi Joao,
First post here, but long time reader. I am interested in how your fuel breather pipe replacement turned out. Did you get it replaced? What part number did you use? Did you have to remove the tank to fit the replacement pipe? How long did it take you? (Is that too many questions?) I am interested because I just experienced a similar problem in my '09 Puma 110 which is fitted with a 45 liter auxiliary fuel tank. After filling from a quarter tank and putting in 90 liters of fuel, diesel began spewing out the top of the tank. I guess that when the main tank filled and the auxiliary tank began to fill, the fuel in the auxiliary tank began to shoot out the top of the main tank through the fuel breather hose. If you could relay any lessons learned, it would be helpful to me as I begin to search for a fix. Best Regards and thanks to all for providing the "unofficial instruction book" for the Defender.

As posted before after reading the OP by Joao, I checked my own fuel breather pipe on my almost 5 year old SVX, and yes, a lot of cracking at the top end on mine too, but no leaks yet. Yesterday my dealer during a scheduled service replaced the cracked pipe on my request as preventive maintenance. As per my earlier post in this thread, remember that my dealer confirmed that still two weeks ago they had to replace this same pipe on another Defender, but that one had developed a bad fuel leak at the bottom end where it is connected to the fuel tank. The actual replacing was no big deal for the dealer, they just had to loosen two supports/brackets holding up the fuel tank and lower this one so that they created proper access space to undo and redo the lower end of this pipe. The old one after taking off, indeed showed numerous cracks and even a real 3 to 4 cm long split at the bottom end too. The split was not to the point of leaking yet, but that was clearly a problem in the making... I cannot easily take a picture of the cracks on the old pipe, as after it has been removed there is no pressure on the ends anymore, so the cracks and the split have closed up again, but they are a fact.
The new pipe freshly installed is cracks free on the top, cannot see the bottom end, but presume the same. Hopefully it is good for another 4/5 years before next replacement.
My recommendation would be that you check the top end of the pipe, and if serious cracks are there, fair chance that same will exist at bottom end too..... For those who are interested in taking the same preventive action here are a few pictures of the correct part number, of the old pipe which was taken off and which I asked to leave with me so that I could show it here, and of the new top collar installed showing no cracks.

My 07 DC has just started leaking from the area of the bottom end of this pipe. I was quoted the Ģ70-ish +vat price for the hose but there is a note in the parts catalogue "cut length as required" so I suspect that your Ģ84 gets you 10 metres or similar of hose, at least I hope so because otherwise it's Ģ5 per inch!
I've noticed that some photos show the tank breather (small hose) teed from the filling breather and others show it as a seperate pipe altogether. Is this a 90 / 110 difference, or can someone explain? The large breather hose is apparently 19mm (3/4") I'D, and the small breather pipe is 10mm (3/8"), according to a thread about fitting a Webasto FBH I found. Major hassle to change since even to drop the tank enough to get a hand in half the towing gear has to come off. |

Further to my previous post, I have established that it's a plain hose (no tee) on my DC. I have also found that it is possible to get one hand onto the tank connection so it might, just might, be possible to change the hose without dropping the tank. The main problem I can see is that the original is held on with a crimped ring not a hose clip and there may not be enough room to get a tool in to cut it.

For those interested I can now confirm that it is possible, though not easy, to replace this breather without dropping the tank, because I did it yesterday evening.
I bought a 1-metre length of 3/4 bore marine fuel hose from a local hose specialist, together with some stainless "Jubilee" clips, the whole lot costing about Ģ20. Access to the tank end of the breather is abysmal, but it is just possible to get your hands to it (I have faily large hands which is a disadvantage for this - if you have competent child labour available I suggest a spot of bribery). The original pipe is secured with some kind of non-reusable crimped clip or ring, and the only way I could remove the clip was with a hacksaw blade. This part of the job took longer than all the rest put together, and was no fun a all. One the hose was off, it was clear that it was very split at the tank end. The new hose is much higher quality than the original and slightly less flexible and squashy. When I tried to feed it through the gap between the chassis and the rear floor (where the original hose is squashed anyway) it became apparent that there needs to be quite a kink to take the hose down to line up with the spigot, and this is exactly where the original hose split (and doubtless the reason it split). I therefore opted to re-route the breather so it passes through the same chassis gap that the filler pipe uses, where is is a much more comfortable fit. This does however mean the the breather pipe now dips downards from the tank then up to the filler orifice assembly, and it is possible that this may affect filling performance if fuel enters and sits in the low spot. Or it may not! I will update this thread if it seems to cause a problem. it is possible to secure the new hose at the tank end with a "Jubilee" clip, but to do so really requires a 1/4" drive socket with a long flexible extension (one of those that is like a long spring) - it would be very difficult to do it without. |
